A position detection apparatus is mounted in a vehicle, and communicates wirelessly with a mobile terminal of a target person to be notified, and thereby detects a relative position of the mobile terminal. The position detection apparatus is provided with: a satellite signal receiver receiving a positioning signal; a correction signal receiver receiving a correction signal; a terminal position communicator receiving by wireless communication from the mobile terminal the acquired positioning signal of the mobile terminal; and a corrected-position calculation portion correcting the received positioning signals of both the mobile terminal and the satellite signal receiver using the correction signal, and calculating the positional relationship of the mobile terminal in relation to the vehicle on the basis of the vehicle position information and the terminal position information based on the corrected positioning signals.
